Consider the following statements: (i) Address Resolution Protocol (ARP) provides a mapping from an IP address to the corresponding hardware (link-layer) address. (ii) A single TCP segment from a sender S to a receiver R cannot carry both data from S to R and acknowledgement for a segment from R to S. Which ONE of the following is CORRECT?

Let us analyze the given statements:

1. Statement (i): The Address Resolution Protocol (ARP) is used at the network layer / data link interface to dynamically map a given network-layer IP address to its corresponding physical/hardware (MAC or link-layer) address within a local network segment. Therefore, statement (i) is TRUE.

2. Statement (ii): TCP is a full-duplex protocol and supports piggybacking. A single TCP segment can contain payload data being sent from $S$ to $R$, while also having the ACK control flag set and carrying an acknowledgment number for data previously received by $S$ from $R$. Thus, it *can* carry both data and an acknowledgment. Therefore, statement (ii) is FALSE.

Hence, statement (i) is TRUE and (ii) is FALSE, which corresponds to Option (B).
